Specially interested in chickens
Mine strongly prefer Purina all flock. Literally they ignored other brands.
I hope it works quickly for your legbar. Chick starter/grower is another option for higher protein feed.
Mine get a mix of grower & layer with the oyster shell on the side, when I have only adult birds, so that they get a better balance of protein. When we have broody hens and chicks, everyone gets the 22% chick crumbles and they all prefer it.
The only downside to a higher protein feed I think is if older birds have troubles with their heart or if they develop gout.
